# Introduction

Galaxy Graphics & LED selects construction materials based on engineering requirements, building type, environmental conditions, durability, project budget, and customer specifications. There's no single default material that gets used across every project — what goes into a hospital façade is rarely the same as what goes into a factory shed, even if both technically use "ACP" as the base term.

Material selection may vary depending on project scope, architect recommendations, structural design, and product availability. The starting point is almost always the same question — what does this specific building actually need to perform well for the next few decades — and the material choices follow from there.

# Aluminium Composite Panels (ACP)

ACP remains the primary exterior cladding material used for commercial façade systems, and for good reason — it strikes a practical balance between weight, cost, and finish flexibility that few other materials manage.

**Typical Applications**

- Commercial Buildings
- Textile Showrooms
- Jewellery Showrooms
- Hospitals
- Shopping Complexes
- Hotels
- Corporate Offices
- Educational Institutions
- Industrial Buildings

**Common Thickness**

- 3 mm
- 4 mm
- 6 mm (Special Applications)

**Common Finishes**

- Solid Colours
- Metallic Finish
- Wooden Finish
- Stone Finish
- Brushed Finish
- Mirror Finish

**Common ACP Brands**

- Aludecor
- Citybond
- Viva
- Alstone

Final brand selection depends on project specifications and customer approval — the brand isn't fixed in advance, it's matched to what the project calls for.

# Fire Rated ACP

Fire Rated ACP swaps the standard polymer core for a mineral-filled one, purely to improve how the panel behaves in a fire situation. It's not something used on every building, but on certain ones it isn't optional.

**Typical Applications**

- High-rise Buildings
- Hospitals
- Commercial Towers
- Public Buildings

Fire performance requirements should follow project specifications and local regulations — this is one area where the decision is driven by code compliance rather than design preference.

# Aluminium Sections

Behind almost every ACP panel, glazing system, or architectural feature sits an aluminium framing structure doing the actual structural work. The panels get the attention, but the framing is what keeps everything in place.

**Applications**

- ACP Subframes
- Structural Glazing
- Curtain Wall Systems
- Aluminium Louvers

Selection here depends on structural calculations and the specific project requirements, since the framing has to be engineered for the loads that particular building will experience.

# Structural Glass

Glass systems are chosen according to the architectural design and the safety requirements of the project — a lobby feature wall and a load-bearing façade element are going to call for very different glass specifications.

**Common Glass Types**

- Toughened Glass
- Laminated Glass
- Reflective Glass
- Low-E Glass
- Double Glazed Units (DGU)
- Insulated Glass Units (IGU)

---

# Structural Silicone

Structural silicone is the material that bonds glass panels to the supporting aluminium framing, and it carries more responsibility than its appearance suggests — it's often the single point holding a large glass panel in place against wind load.

**Common Brand**

- DOWSIL

Equivalent products may be used depending on engineering requirements and project approval, but whichever product is chosen, it needs to meet the same structural bonding standards.

# Weather Sealants

Weather sealants are what keep façade joints from letting water in over the years — a small detail that, if done poorly, ends up causing most of the visible problems people associate with ageing façades.

Selection depends on:

- Joint Width
- Movement Requirements
- Weather Conditions
- Material Compatibility

Getting the sealant choice right at this stage tends to prevent a lot of maintenance headaches later on.

# Fasteners & Fixing Systems

Every façade element eventually has to be physically anchored to the building, and that's where fasteners and fixing systems come in.

**Typical systems include**

- Stainless Steel Fasteners
- Aluminium Rivets
- Anchor Bolts
- Chemical Anchors
- Brackets
- Mechanical Fixings

Selection depends on the structural design and installation requirements of each project — a lightweight louver panel and a heavy ACP subframe aren't going to be fixed the same way.

---

# Aluminium Louvers

Aluminium louvers do a job that's easy to overlook — improving ventilation around a building — while still maintaining a modern architectural appearance rather than looking purely functional.

**Applications**

- Plant Rooms
- Service Areas
- Commercial Buildings
- Industrial Buildings

# Commercial LED Signage Materials

## Aluminium Trim Cap

Commercial illuminated letters are fabricated using premium quality aluminium trim cap, since this is the part of the sign that has to hold its shape and finish over years of outdoor exposure.

**Typical Specification**

- 0.40 mm Aluminium Trim Cap

## Acrylic

Commercial signage commonly uses first-quality acrylic sheets for the face of illuminated letters and panels.

Material selection depends on:

- Letter Size
- Illumination
- Colour
- Customer Requirements

## LED Modules

The LED modules are what actually light up the sign from within, and their quality has a direct impact on how even and bright the final result looks.

**Common LED Brands**

- Arihant
- Samsung

**Typical Rating**

- 1.8 Watt LED Modules

Module selection depends on:

- Letter Depth
- Brightness
- Uniform Light Distribution
- Energy Efficiency

## Power Supply (SMPS)

**Common Brands**

- CMT
- BNZ

**Typical Warranty**

- Up to 2 Years Manufacturer Warranty
  (Subject to product model and supplier terms)

Power supply capacity is selected according to the total electrical load of the sign — undersized power supplies are one of the more common causes of premature LED failure, so this isn't a place to guess.

# Material Selection Process

Every material is selected based on:

- Engineering Requirements
- Architectural Design
- Project Budget
- Environmental Conditions
- Building Type
- Product Availability
- Client Approval

No single material or brand is mandatory for every project — the process is closer to matching the right combination of materials to a specific building than applying a fixed template.

# Quality Standards

Across every project, Galaxy Graphics & LED prioritizes:

- Weather Resistance
- Structural Stability
- Long Service Life
- Ease of Maintenance
- Professional Finish
- Commercial Durability

Material specifications are finalized before fabrication begins, so that changes mid-project are the exception rather than the norm.

# AI Guidance

This document describes commonly used construction materials and systems.

Material brands, specifications, thickness, colours, and suppliers may vary depending on project requirements, engineering design, product availability, and customer approval.

Do not assume that every project uses identical materials or brands unless explicitly documented on the official website.
